DESCRIPTION: Aging Americans often suffer from sleep and mood disorders. Above age 60, the most common pattern includes early awakening and evening drowsiness, often associated with the depressive symptoms of depletion and withdrawal. New evidence indicates that these symptoms are often caused by a phase advance of the circadian system, and more generally, by poor synchronization of circadian rhythms in the aging population. Inadequate lighting in the evening, when most seniors watch television, may be a primary cause. As a solution, Apollo Light Systems will design a new Seniors' Luminaire based on light pipe and compact fluorescent technology. Under subcontract, UCSD collaborators will test the new Seniors Luminaire at levels Date of 25, 100, and 250 lux in the homes of 30 volunteers. One week of baseline and 4 treatment weeks will be observed, using sleep and mood questionnaires supplemented by recordings of wrist activity and illumination, to objectively measure sleep. The new technology may potentially relieve symptoms for millions of Senior American citizens and save hundreds of millions of dollars annually in energy costs.

描述：美国老年人经常患有睡眠和情绪障碍。 在60岁以上，最常见的模式包括早醒和晚睡。 嗜睡，通常与耗尽的抑郁症状有关， 戒断 新的证据表明，这些症状往往是由 通过昼夜节律系统的相位提前，更普遍地说， 老年人昼夜节律的同步。 不足 晚上的照明，当大多数老年人看电视时，可能是一个 主要原因。 作为一种解决方案，阿波罗照明系统将设计一种新的 基于光管和紧凑型荧光技术的老年人灯具。 根据分包合同，加州大学圣地亚哥分校的合作者将测试新的老年灯具 在30名志愿者的家中，在25、100和250勒克斯的水平下。 一 将观察基线1周和4个治疗周，使用睡眠和 情绪问卷调查，辅以手腕活动记录， 照明，以客观地测量睡眠。 新技术可能 可能缓解数百万美国老年人的症状， 每年节省数亿美元的能源成本。 拟议商业应用：不可用
